Disappoiting performance

[008Rohit]

What I think is when FRAPS runs, his CPU and GPU gets some load, so the PSU can't supply enough power hence those parts can never give their 100%, hence low FPS.

That's what I'm thinking aswell. (Hoping aswell.

I've seen plenty of people on youtube recording BFBC2 and Modern Warfare 2 with Fraps and getting smooth recordings with more low-end systems than me. So that's why this has been buggering me for some time that people with pretty standard systems could get so impressive results when recording while I can't even record something in Call of Duty 4 without getting a terrible FPS.

I know for a fact that some games will run WORSE when you have more than the recommended cores aka all those thurban users lol.

Thats what i found after doing some google research too

Wondered why he went all quiet ^.^

 

[ScrewySqrl]

the whole i5-2500K vs i7-2600K was moot anyway...he has a previous generation i7-920!
And yeah, a higher quality powersupply than Energon is undoubtably your issue.

Guys, parts don't just lose performance due to inadequate power. It doesn't work like that. If your power supply can't deliver the juice you will get blue screens and artifacting. Please don't replace your PSU it is fine.

The frame rate of fraps can be limited by hard drive bandwidth. See what happens when you record at a lower frame rate and/or half-size.

 

[malteDK]

Well it does occur sometimes that my entire system shuts down if I have too many applications open or during a game.. That might be because of the power supply I'm guessing.

 

[lozz08]

When is the last time you re-installed windows and such? Could be bloatware and registry filth bogging your cpu.

 

[malteDK]

I doubt it. I've had this problem ever since I bought my 5970 card. I used to have a GFX285 and the switch to 5970 was not very noticable in performance.

Probably re-installed my windows when I upgraded to Win7 64-bit about 7-8 months ago, but at then this problem was the same.

 

[lozz08]

Well, a 5970 does pull about twice as much power... It's never a mistake buying a good power supply anyway, I just doubt it will solve the problem that you have.

 

[malteDK]

Okay guys. New problem. 🙁

I bought the Corsair TX650 V2 PSU and installed it today..

Now when I power up the PC it starts up and 1-2 seconds and then shuts down again, and then after 2 seconds it repeats this. On and off all the time. Nothing is happening on the monitor, but all the fans and hardware powers up when I start it.

I've searched on this problem and a lot of the cases it's due to a faulty PSU.. but I was on Corsairs support site and did a Power Supply Test with a paperclip and the PSU seems to work just fine.. Now what could the problem be??

I'm really frustrated here. 🙁

 

[mightymaxio]

Its probably shutting down due to lack of enough power, you shouldve gotten a larger power supply for the stuff you have. Like a 800 watt.

 

[malteDK]

You can't be serious?

Why have all the people on this thread then recommended my to buy a 650W power supply? + I've seen people with better rigs then me run on the same PSU.

 

[mightymaxio]

Does the PSU have enough on the rails to support a 5970? The most power hungry card of the 5 series. I wouldve checked a PSU calculator before purchase because I dont think a 650 watt power supply is enough head room for that big of a power draw. Especially because you are overclocking which increases the watts the CPU uses. When the power supply can't draw enough power to power the computer it goes in a loop sometimes where it turns on/off.

Whats the effiencency of the PSU?

Did a PSU calculator test and at 100% Peak usage you need at least a 694 watt power supply, recommended is a 750 watt power supply for headroom and capacitor aging. It also could be if people have the same wattage of power supply, that the effiencency rating of the PSU is over 80% which would let you sometimes pull more power than the advertised peak power load.

 

[malteDK]

Omg.. I can't believe that people recommended me to such a stupid buy.

I just spend like 90 $ on a PSU that I can't use.. Just great!

600w is plenty for a single 5970......

"The card requires you to have a 600 Watt power supply unit at minimum if you use it in a fairly high-end system. We assume you'll overclock your processor and that draws a lot of extra power. That power supply needs to have (in total accumulated) at least 50 Amps available on the +12 volts rails."

Your Corsair PSU has 53A on the 12v Rail: http://www.corsair.com/power-supply-units/enthusiast-series-power-supply-units/enthusiast-series-tx650-v2-80-plus-bronze-certified-650-watt-high-performance-power-supply.html

Shouldn't be an issue at all.

 

[malteDK]

But yet it is?

 

[AdrianPerry]

Something else must be at fault.

Are you sure the wall outlet your using is supplying adequate power? Do you use a surge protection plug?

Is your motherboard properly fixed onto your case using the correct stand off screws?

Other than the screws holding your motherboard down are any other metal components touching the board?

Thoroughly check the hardware you currently have.

There seems to be no other metal touching the motherboard than the screws, and yes the wall outlet was fine for my 750W.

Really don't get it.. I have my CD drive plugged in, 3 harddrives with the SATA plugs, my 5970 with 2 PCI-E plugs, my motherboard with a 24-pin plug and a 8 pin plug.. That's it. Nothing else really to plug in it should seem..

 

[izoli]

Its not a bad system tbh, seems a bit overkill using watercooler for that system though but good for future upgrades.

First off I would advise upgrading your processor, dont be tricked into thinking that the I7 is the best just because it is the most recent. The I5 2500k would beast all over that and can overclock up to 4.5ghz.

Not 100% sure on your GPU, perhaps AP could elaborate on that.

I wouldn't really say this without knowing what he does. If he does any sort of encoding, that i7 would triumph over the i5... I am not sure about his cpu, but my i7 960 is overclocked to 4.5GHz on air and idles@ 36c, gaming load for hours@ >50c, encoding for hours@ >60c[with an occasional break over 60c hitting the max I think I have ever seen it touch 63c](This is all in temperature controlled room)

Using Noctua NH-D13 cpu cooler and Noctua NT-H1 thermal compund

But yeah for just gaming I would agree go wtih i5 2500k

double check the motherboard power. make sure you have the 24-pin in correctly, and the CPU 4 pin as well.

 

[malteDK]

All ready did that several times.. My cpu is a 8 pin though. The plug is named, "ATX_12V_2X" ..

 

[malteDK]

Anyone??

This is really buggering me, and it seems that it's the pc that's the problem now, not the PSU..

 

[malteDK]

No, but I got both the Corsair 650W and 750W now and they both do exactly the same when plugged in.

 

[malteDK]

Yes. Several.

But it worked later this day.. Dunno what should have happend.
